Houston to Paris (Roissy-en-France, Val-d'Oise)
10h 27mgate to gate
The flight from George Bush Intercontinental Airport (IAH) to Charles de Gaulle International Airport (CDG) covers 8,072 km (5,016 miles) and takes approximately 10h 27m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 43°, passing near 51.1° N, 55.4° W at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 8,072 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 10h 02m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 10h 27m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
8,072 km / 805 km/h = 10h 02m airborne
+ 25 min ground = 10h 27m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 14h 41m | 15h 06m |
| Narrowbody jet (A320, 737) | 780 km/h | 10h 21m | 10h 46m |
| Widebody jet (777, 787, A350) | 900 km/h | 8h 58m | 9h 23m |
| Private jet (Gulfstream) | 850 km/h | 9h 30m | 9h 55m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions this plate answers
How long is the flight from Houston to Paris (Roissy-en-France, Val-d'Oise)?
A non-stop flight from Houston (IAH) to Paris (Roissy-en-France, Val-d'Oise) (CDG) takes about 10h 27m. The great-circle distance is 8,072 km (5,016 miles, 4,358 nautical miles), flying north-east on an initial bearing of 43°.
How far is Houston from Paris (Roissy-en-France, Val-d'Oise)?
8,072 kilometres in a straight line over the earth's surface — 5,016 miles or 4,358 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between IAH and CDG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,072 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.
What should I expect on a 10h 27m flight?
Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.
